Cloud Computing and Multitenancy has relationship. Both relies on using a single resource and distribution to multiple clients. Risk in both cases depends. The concept of multitenancy should not be confused with that of multiinstance architecture where separate software instances or separate hardware systems are available in different organizations. Physically they are separated in the second case.
Cloud Computing and Multitenancy
Comparison is only possible when there is some similarity, so is for Cloud Computing and Multitenancy. Even if we use virtualization technology of today’s Red Hat, each server can serve a few users on it compared to a multitenant system. Beyond their efficiency, multitenant services can scale easily and by using them you can reduce costs for both the supplier and the customer. Multitenancy if services such as for Facebook, have been able to grow so quickly at the time of their first development to the increase the number users in millions in a short time. In the field of business services salesforce.com is another famous example of multitenancy. For businesses, institutions usually have stricter requirements for the consumers, a multitenant cloud computing platform is full of disadvantages. And developers of these companies has made the idea even worse for several reasons.
Cloud Computing and Multitenancy : Risks and Reason to Go Worser
Suppose you want to have the guarantee that your Gmail account rests only on servers physically located in the United States for legal reasons. It is very difficult, if not impossible, to ensure this with a multitenant platform. Data privacy laws vary widely from state to state, and cloud computing applications often must be performed by data centers located in different countries.
Cloud Computing platform vendors argue that their software if executed properly, will insulate all user data by configuring the information necessary to access differently for each user, but there is always the lurking risk of hitting errors and mistakes of human.
Dragging in other critical case, assume that a hacker is able to break the encryption of a database managed by a provider of a cloud computing service. If it is a multitenant, there is the possibility that the hacker is able to steal data from dozens or hundreds of different business customers, all stored in the same database.
Cloud Computing and Multitenancy : Conclusion
For many companies and developers, it make more sense to adapt to cloud computing platforms that provide a wide range of choice between functionality enabling the traditional relational database, security and flexibility allows single-tenant software and the flexibility in pricing models of the service.

Why ownCloud is Best Cloud Collaboration Tool can be answered by you after using it and knowing about its powerful back end. Let us see what ownCloud has. ownCloud is an server installable Free Software suite that gives a managable storage space with graphical interface with wide plugins or addons. ownCloud was launched in January 2010 by Frank Karlitschek to provide a free alternative software. Before going to details on Why ownCloud is Best Cloud Collaboration Tool, you can read a guide to install ownCloud on Rackspace Cloud Sites and a handy users guide on ownCloud.
Why ownCloud is Best Cloud Collaboration Tool : Features
You can try ownCloud as live demo on their official website :
ownCloud runs on PHP and can use SQLite, MySQL or PostgreSQL as database. Why ownCloud is Best Cloud Collaboration Tool can not be judged from these points as most online collaboration tool actually are PHP MySQL web application. You can store your files, folders, contacts, photo galleries, calendars on your Cloud Server or Cloud Computing Platform, it supports encryption over HTTP by default. You can increase security by SSL. It has built in support for external cloud storage plus the editing tools, photo viewers are quite good by default. Installation as we have shown in the tutorial is simply very easy.
First it is an Free, Open Software with optional paid official support. The support is good point as enterprise users might need a good dev team and instead of bad third party support. The default features, easy installation, mobile device support makes it the best solution.
However, ownCloud has limitation by their own policy of development. It is not acceptable that the free edition lacks features and developers will develop plugins for free and they will lick the honey by supplying as paid product. We observed what eyeOS did – they had almost the same structure of business. Developers must know that, ownCloud can be a second eyeOS by sudden withdraw of the Free version sucking their work. Definitely, nothing can be compared with the structure and policy of WordPress.org.
